There's a decent picture too but my scanner isn't working right now
The picture shown is also of the bumper pad rear fascia, so the aero one might be a little different?
The previous owner of my car apparently took out the fasteners that hold the bumper to the frame under the taillight housing, and now the taillight housing is caught on the bumper! So now I can't take out the left taillight, and you can't remove the rear bumper without removing the taillights!
